please code in python A local variable in a function is either a parameter or a variable which appears on the left hand side (LHS) of an assignment statement in the function. A variable in a function is global if it is not local, but if you want to assign something to a global variable, g, in a function, then you will need the statement global g. Without the global g statement, assignment, like, g = 5, would make g local. You shouldn't use global variables very often when writing functions, since global variables reduce readability. Occasionally they are useful, such as when you would like to count how often a function is called. Define a global variable, countcalls, and increment it inside the power(x, n) function that you wrote for Q4, so that it counts the number of times the power function is called. Show that it produces the expected number of calls for power(2, 10) and power(5, 10) and power(5, 0), each separately

If a parameter in a function header is preceded by of arguments could be sent in the call and they wil [Select] However, if the s an assignment operator a single star , then any number of arguments could be sent in the call along with [Select] [Select] [Select] two stars their values and they will be treated inside the function as a [Select] , then any number as a

c++ computer language given the function header: void sum(int x=2, float y=3, int z =100) then which of the following is a valid function call? (choose all possible) a.sum(9);   b.sum(a,b,5);   c.sum(a,b);   d.sum();

To accomplish pass-by-reference when passing a nonarray variable to a function, it’snecessary to pass the__________________ of the variable to the function.

complete the function definition withouth local variables so that the function will convert any fuel effeciency measured in mpg to the equivalent metric fuel consumption. thank you!

Write a function called area_circumference_generator that takes a radius of a circle as a function parameter and calculates its circumference and area. Then returns these two results as a tuple and prints the results using tuple unpacking in the function call accorrding to the given format. [Must use tuple packing & unpacking] !! Example1: Function Call: area_circumference_generator(1) Output: (3.141592653589793, 6.283185307179586) Area of the circle is 3.141592653589793 and circumference is 6.283185307179586

Define a function named change_values that takes four integers as parameters and swaps or changes them based on a set of rules. Your Change Function should follow the following rules in the following order: 1. If the second value is an odd number, then it should be swapped with the first number. 2. If the third value is a power of two, then it should be swapped with the fourth value. 3. If the summation of the current values 1 to 3rd (after the above two rules are applied) is equal to the fourth value, then the fourth value should be set to the first value.  Then write a Main program that reads four integers from standard input, calls function change_values() to swap the values, and prints the swapped values on a single line separated with spaces.   Example Input: 1 3 4 0 Example Output: 3 1 0 3

In C++ please

Write a function which calculates the number of tweets that were posted per day. Function Specifications: It should take a pandas dataframe as input. It should return a new dataframe, grouped by day, with the number of tweets for that day. The index of the new dataframe should be named Date, and the column of the new dataframe should be 'Tweets', corresponding to the date and number of tweets, respectively. The date should be formated as yyyy-mm-dd, and should be a datetime object. Hint: look up pd.to_datetime to see how to do this.

in C++ program please: According to Wikipedia: “The International Collegiate Programming Contest, known as the ICPC, is an annual multi-tiered competitive programming competition among the universities of the world.” Moreover, the participants of the contest should be no older than 24. Complete the following function which takes as input two parameters: the current year and the birth year of a student. The function should return the age of the person given the parameters. int calculateAge(int current_year, int birth_year) {

Redesign this solution using functions.  For this lab: You will define a function names main(). You will get input in the main function and pass it to the following functions: milesToKm() FahToCel() GalToLit() PoundsToKg() InchesToCm(). Each function will require that you have a local variable to store the result of the calculation. This result will then be displayed using the print statement from within the function. For this portion of the lab, you will reuse the program you wrote in Lab 5 Part1 A.  Redesign this solution in the following manner:   All of the functions used must now be value returning functions. Put the functions in an external module and let the main program import the module.

In C++ programming lanuage: Normally a function does not have access to a variable defined in another function. However, by using a ________________variable as a parameter, a function may change a variable that is defined in another function.

Ibra Bakery wants you to create a simple python program for calculating cashback offers on cakes for the customers on the occasion of their second anniversary. The program should start by reading customer_name, Number_of_cakes. Then you need to do the following     Create a void function and a parameter that will display “Welcome to Ibra bakery <customer name>”. example: Welcome to Ibra bakery Mohammed   Create a function with return value and with a parameter Number_of_cakes. then input cake_price of each cake. Then calculate Total_price as sum of all the cakes’ prices.   Create a function that will accept Total_price as parameter then compute cashback based on a criterion that if Total_price is more than 10.0 omr, cashback will be 20% of Total_price otherwise no cashback.   Display all the details as output. User-defined function(python)

please code in python. Each problem will be placed in its own function. You will have a main function that calls the function for each problem. For these problems, you will need to use the following string functions: lower, upper, isupper, islower, isdigit, and replace, along with using [ ] to access individual characters. You may use other string functions if you find them useful. You will write a function named computeGCPercentage that accepts a string (representing a piece of DNA) as an input and returns a float representing the Guanine-Cytosine (GC) content percentage. For example, assume that the DNA string GTAACTAGCTTACGTAAC is entered. Because there are a total of 7 characters that are either G or C, and there are 18 characters altogether, the function should return a floating point value equivalent to 7/18 . Requirements Your function:1. Must check to see that there are no other characters in the string other than those specified. If there is, it should print an error message…

Which of the following are benefits of specifying a function's parameters' data type(s)? Choose all that apply. it constructs data of the correct type in the parameter O it conveys the valid types of argument expressions required in a call to the function O it conveys valid operations on parameters within the function's body O it ensures a default value for the parameter when an argument is missing it makes it possible to identify invalid function calls without running the program there are no benefits in specifying a function's parameters' data types

Write a function days_in_month() that returns the number of days in a month. The function has the following prototype: int days_in_month(int month, int is_leap); Month should be an integer value between 1 and 12. The function should return (-1) if an invalid month is input. The variable ‘is_leap’ is 1 for leap years, 0 otherwise.
